4x+5 feet
A square has 4 sides, and all of them are the same size. Because of this, you divide the whole expression by 4, and you’re left with 4x+5.
16x/4=4x
20/4=5
Answer:
x = ±i sqrt(3/2)
Step-by-step explanation:
2x^2+7 = 4
Subtract 7 from each side
2x^2+7-7 = 4-7
2x^2 = -3
Divide by 2 on each side
2x^2/2 = -3/2
x^2 = -3/2
There is no real solution, only imaginary solutions
Taking the square root of each side
sqrt(x^2) = sqrt(-3/2)
x = ±i sqrt(3/2)
Answer:
-180
Step-by-step explanation:
Plug 3 in for x and -6 for y.
36(3) – 8(-6)²
108 – 288 = ‐180
<span>A) m > 0 and b > 0
that's what i think it is. If its not im sorry.</span>
If you want to preserve all of the significant figures, then it's 9.00008 x 10^6 .
